Description
Vynález sa týká kcndenzátoy alkanolamínov s mastnými kyselinami alebo oxyetylovaných mastných amino v a ich zmesí, ktoré sa používajú ako lepiace činidlá do fólií na báze polymérov etylénu a jeho kopolymérov.BACKGROUND OF THE INVENTION The present invention relates to fatty acid or oxyethylated fatty amine alkanolamine condensers and mixtures thereof, which are used as adhesive agents for films based on polymers of ethylene and its copolymers.
Do teraz používané spósoby na dosiahnutie lepivosti u fólií na báze polymérov etylénu a jeho kopolymérov sú charakterizované tým, že sa do základného polymeru priidávajú nízkomolekulové přísady typu povrchovo-aktívnych látok alebo ich amesi. Napr. v Eur. pat. 66-149 sa ako lepiace činidlá používajú glycerol estery kyseliny olejovej. V patente AU 82'91-932'A sa lepivost dosahuje prídavkom polybuténu (o· viskozite 400 až 500 cPs pri teplote 99 °C) alebo· naisýtemých alifatických (cyklodifetických) uhTovodíkov (bieiy olej a pod.).The methods currently used to achieve tackiness in films based on polymers of ethylene and its copolymers are characterized in that low molecular weight additives of the surfactant type or their amide are added to the base polymer. E.g. v Eur. pat. 66-149, glycerol esters of oleic acid are used as adhesives. In AU 82'91-932'A, tack is achieved by the addition of polybutene (having a viscosity of 400 to 500 cPs at a temperature of 99 ° C) or of seventh aliphatic (cyclodiphetic) hydrocarbons (white oil and the like).
Podlá jap. patentu 5 6062-841 zlepšeme lepivosti sa dosahuje prídavkom látok typuPodlá jap. No. 5,6062-841 to improve tackiness is achieved by the addition of fabric type
R-CO-NH—(CH2)n—NH—CO—R‘, kdeR-CO-NH- (CH 2) n -NH-CO-R ', where
R, R‘ sú allkyly s 8 až 29 C a n = 3 až 20.R, R‘ are alkyls of 8 to 29 C and n = 3 to 20.
Další jaip. patent 5 8101-T33A používá ako lepiace činidlá 'zmes kalafúnie alebo tálo2 vého oleja s tenzidmi typu glycerín esterov mastných kyselin, sorbiían esterov mastných kyselin, alkylbenzénsuifónanu sodného a pod.Another jaip. U.S. Patent No. 5,801-T33A uses a mixture of rosin or talc oil with surfactants such as glycerin fatty acid esters, sorbate fatty acid esters, sodium alkylbenzene sulfonate and the like as adhesives.
V ďalšom jap. patente 5 2107-043 sa ako lepiace činidlá používajú alifatické uhlovodíkové živice, polyterpény, aromatické petrolejové živice a pod. Pre zlepšenie ich idispergovatefností v záklaldnom polyméri sa přidává 0,1 až 2 diely neiénového tenzidu. Použitím vyššie uvedených činidlel sa dosiahnu u fólií dobré lepiace vlastnosti. Činidlá výrazné negativné neovplyvňujú spracovanie a zlepšujú úžitkové vlastnosti fólie.In the next jap. No. 5,210-0-043, aliphatic hydrocarbon resins, polyterpenes, aromatic kerosene resins and the like are used as adhesive agents. 0.1 to 2 parts of a non-ionic surfactant is added to improve their dispersibility in the base polymer. By using the above reagents, good adhesive properties are obtained for the films. The reagents do not significantly affect processing and improve the performance of the film.
Nevýhodou popísaných riešení je, že sa musí do základného polymeru přidávat' vačšlnou zmes viacerých popísaných činidiel, čo je náročné na speciálně dávkovacie strojně zariadenie a komplikuje tiež zvládnuti© vlastného technologického procesu. Do polymeru sa tiež zabudovává viac culdzích látok, čo je na závadu pri konečnej aplikácii a sťažuje kontrolně metody a analytické postupy. Tiež z hygienického· hladiska je vhodné přidávat do polymérov čo najmenej extrahovat elných přísad.A disadvantage of the described solutions is that a major mixture of several of the described reagents has to be added to the base polymer, which is demanding on a special metering machine and also complicates the handling of the process itself. Also, a plurality of foreign substances are incorporated into the polymer, which is a defect in the final application and makes control methods and analytical procedures more difficult. Also, from a hygienic point of view, it is desirable to add as little extract as possible to the polymers.
Tieto nedostatky odstraňujú lepiace činidlá pre fólie na báze polymérov etylénu a jeho kopolymérov, ktorých podstata spočívá v tom, že alko lepiace činidlá sa ipoužíva250874 jú kondenzáty alkanolamínov typu mono-, di- a trietanolamínu alebo izopropanolamfnu s nasýtenými mastnými kyselinami s párnym počtom uhlíkov v molekule v rozsahu Cs až C24 alebo nenasýtenými mastnými kyselinami s párnym počtom uhlíkov v molekule v rozsahu Cjlb až C24 a jednou alebo dvoma vazbami —C —C— v molekule alebo oxyetylované mastné aminy typu Rí-,CH2~NH-(CH2-(CH2-O)x-H aleboThese drawbacks are eliminated by adhesives for films based on polymers of ethylene and its copolymers, which are based on the fact that alcohol adhesives are used 250874 as condensates of alkanolamines of the mono-, di- and triethanolamine type with saturated fatty acids with an even number of carbons in the molecule in the range of C 8 to C 24 or unsaturated fatty acids with an even number of carbons in the range of C 11b to C 24 and one or two bonds of "C" in the molecule or oxyethylated fatty amines of the type R 1 -, CH 2 - NH- (CH 2 - O) x -H or

Rl, R2 sú nasýtené alkyly s párnym počtom uhlíkov v molekule Cio až C20 alebo nenasýtené alkyly s párnym počtom uhlíkov C14 až C28 a jednou alebo dvoma vazbami — c = C— a x ~ 1 až 30 alebo ich zmesí v množstve 0,3 až 5,0 % hmot., s výhodou 1 % ako přísady do· polymérov etylénu a jeho kopolymérov, zvyšujúce ich lepivost.R1, R2 are saturated alkyls having an even carbon number of C10 to C20 or unsaturated alkyls having an even number of carbon atoms C14 to C28 and one or two bonds - c = C- and x ~ 1 to 30 or mixtures thereof in an amount of 0.3 to 5 0% by weight, preferably 1%, as additives to the polymers of ethylene and its copolymers, increasing their tackiness.
Ako základný ipolymér sa používá najmá rPE (ITT 0,2 až 7 g/10 min] etylén-vinylacetátový kopolymér s ITT — 0,2 až 10 g za 10 min a obsahom vinylacetátu 4 až 30 percent hmot. alebo ich zmes.The basic ip polymer used is at least rPE (ITT 0.2 to 7 g / 10 min] ethylene-vinyl acetate copolymer with ITT - 0.2 to 10 g per 10 min and a vinyl acetate content of 4 to 30 percent by weight or a mixture thereof.
Lepivost látok podlá tohto vynálezu sa hodnotí ako blokovacia sila (N), ktorá je potřebná na oddelonie dvoch pásikov plochej fólie, Iktoré sú překryté na ploché 5 X X 5 cm. Meranie sa robí na trhacom stroji viackrát a výsledkom merania je ich priemerná hodnota. Vzorky fólií sa před meraínm kondioiujú pri teplote 22 °C a relatívnej vlhkosti 40 % počas 24 hodin.The tackiness of the substances according to the invention is evaluated as the blocking force (N) required to separate the two sheets of flat foil which are overlaid on a flat 5 X X 5 cm. The measurement is performed several times on a shredder and results in an average value. The film samples are conditioned at 22 ° C and 40% relative humidity for 24 hours prior to measuring.
Výhody spočívajú v tom, že požadovaná lepivost u fólií na báze ipolyméru etylénu a jeho kopolymérov sa dosahuje iba přídavkem jediného činidla, takže základný polymer možno aditivovať bez váčších problémov už počas jeho výroby v jednom stupni, čo je z híadiska ekonomického, priestorového i úspor energií velmi důležité. Okrem toho' činidla podlá tohto vynálezu pósobia v dosledku dohřej dispergovatelnosti súčasne ako vnútonné niazadlá v tavenine polymérov etylénu a jeho kopolymérov, čím zlepšujú ich spracovíatefské vlastnosti.The advantage is that the required tack of the films based on the ethylene ip polymer and its copolymers is achieved only by the addition of a single agent, so that the base polymer can be additivated without major problems during its production in one stage, which is economical, spatial and energy saving. very important. In addition, the agents of the present invention act as a dispersible agent simultaneously in the melt of the polymers of ethylene and its copolymers, thereby improving their processing properties.
Použitím týchto činidiel sa dosiahne zrovnateTný, resp. vyšší lepiaci účinok ako u doteraz používaných. Tieto látky isúčasne zlepšujú elektrické vlastnosti fólií (povrchový odpor rádu 109—1010Ω), čo předurčuje použitie fólií aditivo váných látkami podfa tohto vynálezu na balenie pomocou baliácioh automatov.The use of these reagents results in a comparable or comparable process. higher adhesive effect than the hitherto used. At the same time, these substances improve the electrical properties of the films (surface resistivity of the order of 10 9 -10 10 Ω), which predetermines the use of the films additive with the substances of the present invention for packaging by packaging machines.
